    摘要: A foot switch for systems such as laser surgery systems. The foot switch utilizes a base, a signal generator connected to the base and a cover rotatably connected to the base in such a way that the cover can be rotated from a first closed position to a second open position. Thus the foot switch is compact and light weight.

    摘要: Reconditioning a fiber for laser applications by cleaving off its tip and shaping the cleaved end into a conical or pyramidal shape with a grinder. The cleaved end is grasped in a fiber holder. The grinder is driven, e.g., to rotate. The fiber holder is moved relative to the grinder to bring it into contact with the moving grinder. The fiber holder may be rotated during the contact. Preferably, the axis of symmetry of the fiber is substantially parallel to the plane of rotation of the grinder to effect tangential grinding.

    摘要: The invention relates to apparatus and methods for transforming a spatial mode of an optical signal. The apparatus includes an optical phase element for imparting a predetermined spatially selective phase delay to the optical signal, and a mask in optical communication with the optical phase element. The mask, in one embodiment, includes an optically attenuating region disposed in a predetermined spatial pattern. In one aspect of the invention, the optical signal is transformed from a first spatial mode to a second spatial mode. In another aspect of the invention, the mask includes an absorbing material arranged in a predetermined spatial pattern. In yet another aspect of the invention, the mask includes a scattering material arranged in a predetermined spatial pattern. The invention also relates to a method for transforming a spatial mode of an optical signal. The method includes the step of receiving the optical signal having a first spatial mode with an intensity distribution and a phase. The method further includes the steps of selectively spatially attenuating the intensity distribution of the first spatial mode of the optical signal, selectively spatially delaying the phase of the optical signal, and propagating the selectively spatially attenuated and delayed optical signal. The first spatial mode of the optical signal is substantially transformed into a second spatial mode.
